I'm using CodeIgniter for my project, and I put this code under Controller as a function like this :

` public function barcode($barcode_data) { // print_r($this->input->get()); /*

and I call the function like this : $barcode_data = [ 'filepath' => null, 'text' => '1234567', 'size' => 60, 'orientation' => null, 'code_type' => 'code128', 'print' => true, 'sizefactor' => null ]; $barcode = $this->barcode($barcode_data);

and used it in here ` <!DOCTYPE html>

Please Save This Code

why is it showing weird string like this barcode
